§24-236 Motor vehicles. (a) Motor vehicles, other than motorcycles, with a
maximum gross weight of 10,000 lbs. or less. No person shall cause or permit any motor vehicle, other than a motorcycle, with a maximum gross weight of 10,000 lbs. or less to operate on a public right-of-way where the muffler or exhaust generates a sound that is plainly audible to another individual at a distance of 150 feet or more from the motor vehicle.

Fight it..generate some evidence that it wasn't audible from over 150 feet.
